ACHIEVING THE SEA POWER 21 VISION AND ENVIRONMENTAL STEWARDSHIP FOR TOMORROW'S SHIPS


By Mary Jo Bieberich

WEST BETHESDA—Scientists and engineers in Code 60’s Environmental Quality Division are leading the environmental protection, safety, and occupational health (ESOH) planning and systems engineering efforts for several of the Navy’s major ship acquisition programs. They include CVN 21, LHA(R), DD(X) and T-AKE.

Working in partnership with shipbuilder design teams, Code 63 personnel manage integrated product teams and working groups, develop and implement environmental protection and pollution prevention strategies, assess feasibility of new waste management and treatment technologies, review design documents, and identify ESOH risks and risk mitigation strategies. Their mission is to enable ships of the future to meet the U.S. Navy’s new operational concepts, as articulated in the Chief of Naval Operations’ Sea Power 21 vision, while achieving environmental stewardship.

Persistence, power and presence will be the hallmarks of CVN 21. Slated to begin construction in 2007, it represents the next step in the Navy’s evolutionary carrier strategy. Today, CVN 21 is in preliminary design. Detailed to the CVN 21 Design Team (SEA 05DC) are Douglas Vaughters (634), Deputy Ship Design Manager for Machinery Systems; Henry Molintas (634), Auxiliary System Support Engineer —Pollution Abatement Systems; and Robin Hays (632), ESOH Manager and Principal for Safety. Their accomplishments include the first ever ESOH specification for an aircraft carrier, the implementation of a risk-based ESOH ship systems engineering process, and the development of a NEPA strategy for CVN 21. Comprehensive reviews of conceptual design/block diagrams for environmental protection systems have also been conducted. A plasma arc waste destruction system for solid waste and a pollution control fluids system for the collection and treatment of oily wastewater are two new and innovative waste management systems planned for CVN 21.

LHA(R) will be the replacement amphibious assault ship for the LHA Class. Designed to project power and maintain presence, it will be a cornerstone of the Amphibious Readiness Group/Expeditionary Strike Group, transporting and landing elements of the Marine Expeditionary Brigade. The LHA(R) is currently in functional design. Jim Higgins (633) leads the Environmental Systems Design Team in support of the Machinery IPT. For the past year, he has been working with ship subject matter experts and industry to establish design requirements and identify and evaluate candidate waste management and treatment technologies. One key design decision that has been made by the team is to incorporate a vacuum collection, holding and transfer (VCHT) system for sewage and graywater. In contrast to the gravity CHT system on the baseline ship, LHD 8, VCHT will significantly increase sewage and graywater holding times, enabling extended periods of littoral operations. Additionally, VCHT offers substantial reductions in weight, as well as reductions in acquisition and life-cycle costs.

Leading the ESOH Working Group for LHA(R) is Christian Adamoyurka (634). His responsibilities encompass the integration of five key elements of ESOH into the systems engineering process: environmental compliance, pollution prevention, systems safety, risk identification, and NEPA. Supporting Adamoyurka is the Environmental Manager, Melissa Ramirez (634). Adamoyurka and Ramirez report directly to the PMS 377 ESOH Integration Manager. A Hazardous Material Management Program Plan, a Demilitarization and Disposal Plan for the Class, and a Programmatic Environmental, Safety and Health Evaluation (PESHE) are among several products developed by the working group.

DD(X), a key enabler of the Sea Power 21 vision, will deliver a vast range of warfighting capabilities that will transform the combat capability of the Fleet. The DD(X) Program, currently in Phase III of spiral design, has successfully completed its preliminary design review (PDR). Acquisition Milestone B and Critical Design Review (CDR) are scheduled for FY 05.

George Filiopoulos (632) serves as the Environmental Manager for DD(X) and, with his Bath Iron Works counterpart, co-chairs the DD(X) Environmental Working Group. For the past four years, Filiopoulos has provided technical expertise in all phases of environmental protection to PMS 500 and DD(X) design agents to ensure that environmental compliance and pollution prevention are fully integrated into the ship’s design. With this focus, he has provided the environmental requirements that are guiding the development of DD(X) system specifications and the coordination among government and industry communities essential for a successful acquisition program.

Named after two explorers who led a visionary project that was to become one of America’s greatest adventure stories, the first ship of the T-AKE Class, USNS Lewis and Clark, is in the latter phases of detail design, in transition design, and production. This new underway replenishment vessel will operate independently for extended periods at sea, providing replenishment services to U.S. and NATO ships and directly contributing to the ability of the U.S. Navy to maintain a forward presence. Mary Wenzel (632) led the ESOH efforts through functional and preliminary design and is returning to the program office (PMS 325) to manage ESOH, system safety, and human engineering design activities through transition design and production. Under Wenzel’s leadership the T-AKE Program was the first acquisition program within the DoD to develop and implement an ISO 14001-certified environmental management system, gaining Secretary of Defense and Secretary of Navy recognition.

The Environmental Quality Division is working in concert with the U.S. Navy’s acquisition community to enable the Fleet of the future to meet the global operational objectives of Sea Strike, Sea Shield, and Sea Basing with minimal impact on the environment. Ships equipped with efficient and effective waste management systems are more agile, more sustainable, less vulnerable to attack, and less reliant on shore infrastructure, thus supporting the capabilities-based approach of Sea Power 21.
